A18A17
Notes:
The Digitrip 1150 front panel is used to program the external module for any
combination of the following: Aux Switch, BELL Alarm, INST ,SDT, LDT
GndT or GFAlm, HLAlm, DEADman, WATCHDOG, ALARM, (the Alarm relay
tracks the function of the Aux ReLaY A programming).
Each module has 4 relays. Each relay has a form C contact with each having a
rating of 10A max @ 250 VAC.
Control voltage is 120 VAC ± 20% or 48 - 125 VDC.
Accessory Bus Modules use DIN rail mounting. Connector types are
plug-in-Phoenix . Four form C contacts use 12 pin connector part # 1835193.
Power is 5 pin part # 1835122.. Communication.. is 3 pin. Part # 1835106.
Communication Cable is C-H style 2A957805G01 or Belden 9463 cable.
Set switch to corresponding adress(001 through 004) programmed via the Digitrip
