Series Overview
Series Overview
Multifunctional Three - phase Control Relays RM22TA, RM22TU, RM22TR and RM22TG
Introduction
- The RM22 multifunctional Harmony control relay monitors the following functions for three - phase power supplies:
| Function | RM22TA | RM22TU | RM22TR | RM22TG |
|---|---|---|---|---|
| Sequence of L1, L2 and L3 | YES | YES | YES | YES |
| Missing phase | YES | YES | YES | YES |
| Phase asymmetry | YES | |||
| Under - voltage | YES | |||
| Over - voltage and under - voltage | YES |
According to different models, the RM22T●● control relay:
- Can accept various rated three - phase voltages: Up to 480V~
- Monitors the actual effective value (rms) of its own power supply (except for RM22TG)
- The relay can be installed on a DIN rail
Their features include:
- Setting protection with a sealable cover
- Diagnostic button for load circuit testing
- Relay output status LED
- Fault diagnosis display LED
- Rotary pointer LED indicating the relay power - on (ON) status
- Relay output opens with delay and closes with delay
Applications
- Control the connection of mobile equipment (field equipment, agricultural equipment, refrigerated trucks)
- Control function to prevent reverse rotation of motors (hoists, lifting, elevators, escalators, etc.)
- Sensitive three - phase power supply control
- Emergency power supply switching in abnormal situations
Single - phase Voltage Control Relays RM22UA and RM22UB
Introduction
- RM22UA and RM22UB single - phase or DC voltage control relays monitor the following functions:
| Function | RM22 | UA2●MR | UA3●MR | UA33MT | UB34 |
|---|---|---|---|---|---|
| Over - voltage (no memory) | YES | ||||
| Over - voltage or under - voltage (with/without memory) | YES | YES | |||
| Over - voltage or under - voltage (window mode) |
RM22 control relays allow:
- Automatic identification of AC and DC
- Can choose over - voltage and under - voltage
- Monitor the actual effective value (rms) of its own power supply
- Can choose memory function
- Can be clipped on a DIN rail
Their features include:
- Rotary pointer LED indicating the relay power - on (ON) status
- Relay output status LED
- Setting protection with a sealable cover
- An LED indicating the control status
Applications
- Protect electronic or electrical equipment from the effects of over - voltage and under - voltage
- Emergency power supply switching in abnormal situations
- Speed control of DC motors
- Monitor AC or DC power supplies
- Battery and speed monitoring (with tacho generators)
Single - phase Current Control Relay RM22JA
Introduction
- The RM22JA multifunctional current control relay monitors the following functions:
| Function | RM22JA21MR | RM22JA31MR |
|---|---|---|
| Over - current (no memory) | YES | |
| Over - current (with/without memory) | YES | |
| Under - current (with/without memory) | YES | |
| Over - current and under - current (with/without memory) (window mode) | YES |
These relays can:
- Automatic identification of AC and DC
- Can choose over - current and under - current
- Measure the actual effective value (rms)
- Can choose memory function
- Can be clipped on a DIN rail
Their features include:
- Rotary pointer LED indicating the relay power - on (ON) status
- Relay output status LED
- Setting protection with a sealable cover
- An LED indicating the control status
Applications
- Excitation control of DC motors
- Control the load status of motors and generators
- Control the current flowing into three - phase motors
- Monitor heating or lighting circuits
- Control pump discharge operations (over - current)
- Control situations where the force is too large (crushers)
- Monitor electromagnetic brakes or clutches
Liquid Level Control Relays RM22LA and RM22LG
Introduction
- RM22LA and RM22LG liquid level control relays control one or two liquid levels through inlet or outlet functions:
| Function | RM22LA 32MR | RM22LG 11MR/11MT |
|---|---|---|
| Liquid level 1/liquid level 2 | YES | YES |
| Inlet operation | YES | YES |
| Discharge operation | YES | YES |
| Low sensitivity | YES | |
| Standard sensitivity | YES | YES |
| High sensitivity | YES |
The features of RM22 liquid level control relays include:
- LED rotary pointer indicating the relay power - on (ON) status
- LED indicating the relay output status
- Setting protection with a sealable cover
- An LED indicating the control status
- These relays are installed on a DIN rail
Applications
- These devices can monitor the liquid level of conductive liquids
- These devices control the start of pumps or valves to adjust the liquid level, and can also prevent the idling of submersible pumps or prevent the “overflow” of liquid containers. In addition, they can be used in mixing processes to control the flow of liquids and protect heating components in non - submerged environments
- There is a transparent protective cover on the front panel of these devices, which can prevent incorrect setting operations. This cover can be directly sealed
Examples of compatible liquids:
- Spring water, domestic water, industrial water and seawater
- Metal salts, acid or alkali solutions
- Liquid pesticides
- Non - concentrated alcohol (> 40%)
- Liquids used in the food processing industry: Beer, coffee, etc.
