I. Product Overview (Core Parameters)

1) Basic Specifications

Model: 9563-810 (Digital Input Termination Panel, Isolated)

Input: 24VDC circuit, supports dry contacts / wet contacts (NPN/PNP)

Channels: 16 digital inputs / board; 32-point DI module requires 2 boards (1–16, 17–32)

Isolation: ≥ 1500VAC field - system isolation, anti-surge, anti-interference

Protection: Each channel 1A slow-blow fuse, with FUSE fuse blow indicator

Common Terminal: Non-common terminal (isolated type), each channel independent circuit (key difference from 9561-810)

Architecture: Compatible with TMR triple redundant I/O, signal voting to prevent single-point failure

Safety Level: SIL3 (IEC 61508)

Temperature: -40℃ ~ +70℃ (industrial wide temperature)

Certifications: CE, UL, CSA, ATEX/IECEx (explosion-proof available)

Installation: 35mm DIN rail / panel mounting, green terminal block

Compatible Modules: 3503E, 3505E (32-point TMR digital input module)

Connection Cables: Special flat cables (same as 9561-810, such as 9562-810)

2) Panel Indicator Lights (3 types, clear diagnosis)

CH01–CH16 (Green): Lit when corresponding channel input is closed

PWR (Green): Normal 24VDC power supply on the terminal board

FUSE (Red): Lit when any channel fuse blows (single-channel positioning)

3) 9561-810 vs 9563-810 (Quick Differentiation at a Glance)

9561-810: 32-point common terminal (shared ground), low cost, suitable for centralized power supply scenarios

9563-810: 16-point isolated (non-common terminal), strong anti-interference, suitable for explosion-proof / strong interference / independent circuit scenarios

II. Usage Instructions (Installation / Wiring / Maintenance)

1) Installation Configuration

32-point DI module (3503E/3505E): Must be paired with 2 9563-810 (1–16, 17–32)

Installation Location: In the cabinet, DIN rail, close to the field wiring side; connected to the I/O module through flat cables

Installation Procedure: Rail insertion type, snap fastening; supports hot swapping, online replacement without downtime

2) Wiring Specifications (Isolated Type, Each Channel Independent)

Dry contacts: Channel + → one end of the switch, Channel - → the other end of the switch (no common ground)

Wet contacts (24VDC): +24VDC → Channel +, 0V → Channel -, switch connected in the circuit

Wire Diameter: 1.0–1.5 mm² multi-strand copper wire, crimped cold press terminals

Fuse: Built-in 1A slow-blow, overcurrent protection; FUSE light on indicates replacement of the corresponding fuse

3) Operating Status

Normal: PWR constantly lit, CH lights turn on and off according to the input status, FUSE fully off

Redundancy Synchronization: Automatically synchronized with TMR module, no disturbance switching

4) Fault Handling

FUSE lit: Investigate corresponding channel short circuit / overload, replace 1A fuse

CH not lit: Check the field switch, wiring, 24VDC power supply

PWR not lit: Check the power supply circuit, flat cable connection

III. Quick Reference for Series Selection
