Relay Alarm/Digital Input Specification

Minitrend QX and eZtrend QXe recorders have one 'slot' for digital inputs and alarm re-
lay outputs. All alarm card channels provide 240V AC isolation channel to channel and
channel to recorder. Digital I/O channels will provide isolation to 100V AC test voltage (not
for mains connection).
The Multitrend SX recorder has three available expansion slots for Digital Input/Relay
Alarm output cards.
Inputs are automatically debounced to remove switching oscillations. All Digital Inputs are
volt free contacts, and are sampled at 10Hz max.

Relay/Alarm Output Card Options

There are two card options, split into two types:
120/240 VAC 3 Amps rated (resistive load). The relay contacts are form C (NO, NC) and
includes suppression.
120/240V AC 3 Amps rated (resistive load). Two channels on the 8 Relay Alarm card, can
be used as digital inputs. The relay contacts are form C (NO, NC) and includes suppression.
The 8 & 2 Relay Alarm card, this 8-channel card will have 8 mains rated relays, of which 2
of the 8 channels can be configured for use as digital inputs.
