The SSL remote GP IO unit is a 1U rack mounted chassis and is available in two versions that provide either 24 or 48
channels of GP input and output. The chassis features two mains power supplies thus providing ‘
On-Air ’ redundancy.
GP IO boxes are connected to the console surface by a standard Ethernet connection. Connection is made to the SSL
network and should therefore be kept separate from the facility’s IT infrastructure.
Input and output signals can be either latching or momentary; this setting is individually assigned in software via the touch
screen. When set to momentary the input trigger signal duration must be greater than 50mS.
Refer to Section 6-13 for the connector pinouts.
The internal mains power supplies are of the fully isolated type. It is recommended that a separate earthed lead is
attached to the rear of the chassis to ensure a permanent ground connection. An M3 threaded insert is provided on the
rear panel for the ground lead.

Witching
Inputs are triggered by applying a voltage of between 4V and 30V (AC or DC) across each pair of inputs pins. The current
drawn is approximately 10mA.
A 0V reference is available on all input connectors. A protected source of +12V available on all output connectors.

The switch closures are via 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.
If 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 GP Out 1 will be on GP In 1).
