NOTE:
Relay outputs K1 and K2 can be
selected as normally-open or
normally-closed by placing their
jumpers to the NO or NC
position.
2- AND 4-CHANNEL RELAY BOARDS (IQ PLUS 800)
A 2-channel or a 4-channel relay board is available for mounting inside the
IQ plus 800 case.
2-Channel Relay Board
This compact (2.5" x 3.0") output board allows two digital outputs to control
115 VAC or DC services that operate other equipment. Both outputs can be

4-Channel Relay Board
This 3.0" x 4.0" input/output board allows up to four digital outputs to
operate 115 VAC or DC service. Two of the channels have a normally-open
contact output. The remaining two output channels are selectable for either
normally-open or normally-closed. Relay outputs are rated at 3 amps at 115
VAC and .5 amps at 50 VDC. The output contact is fused with a 4 amp fuse.
Up to three AC inputs from equipment in the field can also be wired to the
board to feed into the indicator's TTL-level digital inputs. Inputs are
normally-open in a +5 VDC logic-high OFF condition. When AC voltage is
present , the outputs go to an ON logic-low state.
