Description

Apollo Discovery and XP95 are the protocols open to this card, with 460mA the rating it carries.

Drive reaches 460mA (pulse signalling current), taken from a loop running at 35V - signaling pulses, while the card itself asks 12mA (excluding loop devices). Resistance must stay within 100 Ohm max. and capacitance within 0.5μF max.; with a loop resistance > 40 Ohms, double address detection cannot be guaranteed. Which end of the loop is under drive is shown by two diagnostic LEDs.

795-066-100 is a loop driver card for Apollo Discovery or XP95 Protocols, carrying a 460mA rating. Loop devices on the circuit it drives therefore work to one of those two Apollo protocols. The loop is driven at 35V - signaling pulses, and the card's own consumption is 12mA (excluding loop devices).

Maximum continuous loop drive current is 460mA (pulse signalling current). Circuit limits are 100 Ohm max. resistance and 0.5μF max. capacitance, and double address detection cannot be guaranteed with a loop resistance > 40 Ohms. Two diagnostic LEDs indicate which end of the loop is being driven.

Size is 105 x 54 x 25 mm at 44 gr., with an operating window of 0°C to 49°C and humidity 85% non-condensing. Loop connections are made at motherboard screw terminals in a removable block, for cable of maximum cross sectional area 2.5mm2 (13AWG), and the loop is run as class A or class B in shielded, twisted wire.
