Rio Gp-I/O - Solid State Logic C100HDSS Installation Manual

Section 5
GPI I/O
The Interface card fitted to each RIO unit is equipped with 24 circuits of GPI I/O. Each input is opto-isolated and is
accessed via 25-pin D-type male connectors. Outputs are via relay-closure and are accessed via 25-pin D-type female
connectors. Mating connector kits are available to order.
Both the input and the output circuits are fully isolated from the RIO electronics. On output connectors, there is a
protected source of +15V available an, a 0V reference is available on input connectors.
The input and output signals can be either latching or momentary; this is individually assigned in software using the touch
screen. When set to momentary, the input signal trigger duration must be greater than 50mS.
When used for discrete track arming with associated tally, the tally must return to the same number input as the arming
output signal, (ie. the tally for GPI Out 1 will be on GPI In 1).
The switch closure is by DIL relay. Contact rating is 100Vdc, 125Vac, 100mA max. Do not use the output contacts to
directly switch capacitive or reactive loads; always use an external relay with a suitable contact rating.
The input is triggered by an AC or DC voltage between 4V and 30V. The current drawn is approximately 10mA.
