Note 1.
Inputs can be:
State - i.e. ON or OFF.
Count - 0~50Hz
Note 2.
LED indication per input. LED intensity depends
on voltage level at the input terminals. Refer to
‘
Specifications
’ for input loads.
Note 3.
For scaling of counter inputs, totalising and flow
data conversion, refer to Microscan Configuration
Manual, line setup/counter scaling.
Note 4.
All cables must be screened, with screen earthed
at one end only. Refer ‘The Proper Installation &
Wiring of the 2100-A
16
.’
Note 5.
Do not fit the 4K7 resistor for 3 wire PNP
transducers.
Note 6.
Digital Inputs are not available when used as an
intelligent multiplexer.

Note 1.
Both relays are Normally Open, and share a common.
Note 2.
30Vac/dc, 1A maximum contact rating. For individual relay outputs
(ie not sharing a common) and/or a contact rating of 250Vac, use a
2100-RL2. This is a 2 relay slave board that can be wired directly to
the 2100-A
16
.
Note 3.
Each relay can be configured for a ‘Normally ON’ or ‘Normally OFF’
output state. (E.g. for fail safe operation.) The ‘Normally ON/OFF’
settings are retained in software on power down, but the relays are
de-energized. Refer to MicroScan Configuration Manual.
Note 4.
Relay 2 can be selected as a Comms failure time-out alarm. The
relay is normally active and deactivates after 5mins if no Comms
messages are received. This function does not detect
microprocessor failure. When used for this function the relay
cannot be used for any other function.
Note 5.
LED indication on each output when relay is energized.
Note 6.
For additional Relay Expansion refer 2100-R2.
Note 7.
Digital Outputs are not available when used as an intelligent
multiplexer.
