Table A–Wiring connections
* Bipolar (Voltage Input) is ±150Vdc, Unipolar Voltage (Input) is 0—300Vdc, Temp Probe is 0—20Vdc with power source.
** See Table B for definitions of impedance levels.
*** Can be configured to de-energize on alarm (DOA) or energize on alarm (EOA).
**** System Fail output relay is fail-safe and will de-energize during an alarm condition.
NOTE: DCCT power output is protected against short circuits and is able to power four DCCTs.
To aid the user with installation, frequent reference is made to drawings located at the rear of this manual.
Custom configurations may be detailed within the Argus power system documentation package.
5.7.1 Programming the Digital Input
The digital input channels (terminals 19 through 26) can be programmed for “active high” or “active low.” Active
high indicates “alarm on the presence of a short circuit” and active low indicates “alarm on the removal of the
short circuit.”
NOTE: See CXC Software manual for detailed instruction on programming.
Impedance Level (Ohms)
Considered As “0” (Off) Impedance Level (Ohms)
Considered As “1” (On)
> 1M < 1
