10 - 30 unregulated When optional Voltage Module ( VM ) card is fitted, a -10 to -30Vdc negative supply mayalso be connected to increase current sinking capability and reduce noise. If a negative supply is not connected, the VM card automatically generates its ownUnit can operate indefinitely at 33Vdc and is capable of absorbing short duration transients above this10 maximum (plus output currents from 5Vdc source and current output).
