Field Application & Problem Solved
In the field the biggest headache is landing forty-plus discrete contacts—oil-pressure switches, temperature stats, limit switches—without turning the turbine panel into a rat’s nest. The DS200DTBAG1A solves that by giving you two 95-point screw blocks on one plug-in card. Slide it into the Mark V rack, snap the pre-wired J-plugs onto the DSP board, and you’re done. You’ll typically find this card in 7EA or 9E peaker cabinets where every aux contact in the skid has to report back to the Speedtronic. Core value: it collapses three DIN-rail terminal strips, pull-up resistors, and noise filters into a 6 × 5 inch card you can swap while the unit is on turning gear—no re-labeling, no extra hardware.

Installation & Maintenance Pitfalls (Expert Tips)
Jumpers Installed Backwards = Dead Inputs
The silk-screen is read from the component side; flip the board over and the berg jumpers land on the wrong pads. Result: inputs float high, the DSP sees every contact as open, and you spend an hour chasing “false open” alarms. Match the jumper map in GEI-100161 before you torque the screws.

Terminal Torque 0.8 Nm – No More
Over-tighten and the screw posts crack; under-tighten and vibration walks the wire out. Use a calibrated screwdriver and stop when the washer flattens—then tug-test every wire.

IP30 Means Keep the Door Closed
The front is open; wash-down or salt mist will corrode the screw posts and give you intermittent “contact bounce.” If the cabinet fan ingests salt, bag the card during maintenance or mount it behind a filtered door.

Wire Dress – Flat or the Door Won’t Close
190 wires in a 6-inch slot is tight. Leave the harness proud and the cabinet door pinches a conductor against the sheet-metal—ground fault that trips the whole Mark V. Lace the bundle flat and strap it to the card stand-offs.

Technical Deep Dive & Overview
The card is a passive termination array—no CPU, no firmware. Each input line hits a 10 kΩ pull-up to +24 V, an RC noise filter (≈1 ms), and a 500 V opto-coupler that feeds the DSP a clean TTL signal. Because it’s pure hardware you can hot-swap it: pull the old card, land the wires exactly where they came from, snap the J-plugs in, and the turbine sees all contacts again in under five minutes.
