- Providing redundant alarm outputs for critical rotating machinery
- Turbine trip circuits, compressor shutdown systems
- Power generation, petrochemical, metallurgy, and water treatment facilities
Performance Parameters:
- Channel count: 4 independent relay channels
- Relay response time: Less than 10 ms typical
- Contact life: 100,000 operations at rated load
- Logic combinations: Unlimited AND/OR combinations of rack alarm inputs
Material Composition:
- High-reliability electronic components on multi-layer PCB
- Epoxy-sealed SPDT relay contacts for environmental protection
- Metal module enclosure with conformal coating
- Gold-plated backplane edge connectors
Structural Features:
- Full-height module form factor
- Front panel with OK, TX/RX, and CH ALARM LED indicators
- Rear I/O module (125720-01) with screw terminal connections for relay contacts
- Plug-in design compatible with any accessible rack slot to the right of the Transient Data Interface module
Working Principle:
The 3500/32 module receives alarm status information from all monitor modules in the rack via the backplane bus. Each of the four relay channels has an independently programmable alarm drive logic that evaluates AND/OR combinations of alarm inputs from any channel in the rack. When the programmed logic condition is satisfied, the corresponding relay changes state, providing a hardwired output to external systems.
Installation Requirements:
- Install in any full-height slot to the right of the Transient Data Interface (TDI) module
- Install the corresponding I/O module (125720-01) in the rear slot
- Configure relay logic using 3500 Rack Configuration Software
- Set each channel’s relay to normally energized or normally de-energized mode via the hardware switch on the I/O module
