Over the years sequencing different stages for compressors, staged electric heat strips, actuators, pumps, and various lighting applications has not been the easiest job for the mechanic. Functional Devices, manufacturers of the famous Relay In a Box (RIB relays), has released the RIBMN24Q4C-PX programmable sequencer to make your job easier.
The RIBMN24Q4C-PX is used to control four integrated 15 amp SPDT relay contacts with one (0-10vdc) analog signal. Power input of this control is 24 VAC/DC. Unlike other models, the RIBMN24Q4C-PX has an on-board digital display to eliminate the need to attach a voltage meter. Just dial up your desired trip voltage and move on to the next relay set point!
Relay will activate when control signal voltage reaches or exceeds individual relay setpoint
Turn Off is set to 200mV less than setpoint
Factory relay setpoints: Can be changed by installer
Relay 1: 3V » Relay 3: 7V
Relay 2: 5V » Relay 4: 9V
Minimum setpoint: 0.5V
Maximum setpoint: 9.9V
Relay number will flash 3 times when voltage exceeds setpoint
Pressing UP or DN button in normal run mode will display the voltage present on Analog Input
*Sequencer can be piggy-backed, allowing more than 4 relay setpoints if sequencer 1 and sequencer 2 are using the same power control input and input signal source. At this point the relay setpoints on sequencer 2 can be different or the same as sequencer 1. Note: sequencer requires 5va power draw per sequencer from control transformer.
The RIBMN24Q4C-PX is also shipped with a MT212-6 din rail mounting strip.
Tired of messy installations? Check out the new 550VA commercial UPS along with an enclosure and interface board from Functional Devices which allows the installer to hardwire line voltage to the provided UPS while giving the ability to hardwire the UPS to the final load.
