Triconex |9561-810|Digital Input Termination Panel
Description
The 9561-810 is a termination panel designed for use with 24V digital input modules in Tricon v9–v10 systems. It provides 16 input points and commoned power terminals (PWR+ and PWR–). Each input point is protected by a fuse with a blown-fuse indicator, ensuring reliable operation in industrial environments.
Features
- Compatible with 24V digital input modules.
- 16 input points per panel.
- Commoned power terminals.
- Built-in blown-fuse indicators.
- Supports 32-point modules (requires two panels).
Technical Specifications
Input Points: 16
Power Terminals: Commoned (PWR+ and PWR–)
Leakage Current per Point: Maximum 3.3 mA, Typical 2.5 mA
Fuse Protection: 1A, slow-blow fuse with LED indicator
Operating Voltage: 24 VAC/VDC
Modules Compatible:
- 3501E (24 VAC/VDC, commoned, 32 pts.)
- 3501T (24 VAC/VDC, commoned, 32 pts.)
Field Wiring:
- Designed for AC or DC power supply.
- Each input point must be connected to the field device and the common power terminal.
- Fuses protect against overcurrent conditions, with LEDs indicating blown fuses.
Environmental Conditions:
- Operating Temperature Range: 0 to 60°C
- Storage Temperature Range: -40°C to 85°C
- Humidity (non-condensing): 0 to 95%
Simplified Schematic:
- The panel includes a leg-to-leg bridge AC isolation rectifier and smoothing circuit.
- Threshold detection and opto-isolator ensure reliable signal transmission to the input multiplexer (Input Mux A).
