Notes:
The Digitrip 1150V 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 address(001 through 004) programmed via the Digitrip
front panel.
Set switch up to insert 100 ohm terminating resistor on last relay of network.
