IS400WROGH1A GE MKVIe Contact Wetting Daughterboard

Description:

IS400WROGH1A is GE MKVIe, WROG DIST POWER AND SENSING BOARD

SRLY is available in two groups. SRLY1A comes with fixed box terminals and omits option board connectors JW1 and JW2. SRLY2A uses pluggable type terminals and has connectors JW1 and JW2 supporting option board connection. Electrically SRLYH2 has the following circuit for each of the 12 relays

Without an option board, the SOL terminal associated with each relay has no connection. SRLY is designed to support a current rating of 5 A and voltage clearance greater than is needed for 250 V ac on all customer screw and JW1 circuits. The relay rating is the limiting item for each application.

SRLY + WROB
Option board IS200WROBH1A adds capability to SRLY2A to yield a combination that has the same functionality as an IS200TRLY1B terminal board when used simplex. Included are fused sensed power distribution to the first six relays and dedicated power to the last relay. Electrically IS200SRLY2A plus IS200WROBH1 has the following circuit. IS200WROBH1 has default fuse values of 3.15 A. Connector JW2 and its connections to JA1 are omitted for clarity.

To install the PDIA pack
Installation
The WROG plus a plastic insulator mounts on a sheet metal carrier that then mounts on a DIN rail. Optionally the SRLY plus insulator mounts on a sheet metal assembly that then bolts in a cabinet. The connections are wired directly to two sets of 48 point terminal blocks, typically using #18 AWG wires. The upper set of terminals, TB1, connects to the relay portion of the board and the lower set of terminals, TB2, connect to the contact input circuits. Shields should be terminated on a separate bracket.

Operation
The function and on-board signal conditioning are the same as those on TBCI, they are scaled for 24, 48, and 125 V dc excitation. The input excitation range is 16 to 32 V dc, 32 to 64 V dc, and 100 to 145 V dc respectively. The threshold voltage is 50% of the excitation voltage. The contact sensing circuits are shown in the figure.The processor board in the pack is common to all Mark VIe Ethernet I/O packs. It contains the following:
• High-speed processor with RAM and flash memory
• Two fully independent 10/100 Ethernet ports with connectors
• Hardware watchdog timer and reset circuit
• Internal I/O pack temperature sensor
• Infrared serial communications port
• Status-indication LEDs
• Electronic ID and the ability to read IDs on other boards
• Substantial programmable logic supporting the acquisition board
• Input power connector with soft start/current limiter
• Local power supplies, including sequencing and monitoring
An industry-standard infrared serial communications port is provided on the processor board. Accessible through the pack front, this port provides diagnostic information on the pack status and an ability to program the pack when both Ethernet connections fail. It is possible to communicate with this port using most notebook computers and most hand-held Personal Digital Assistants (PDA).
