1734-IB8S SER-B Type Allen Bradley 8-point I/O Module with Diagnostic and Short-Circuit Protection Functions

  1734-IB8S SER-B Type Allen Bradley 8-point I/O Module with Diagnostic and Short-Circuit Protection Functions

1734-IB8S is a POINT I/O safety input module produced by Allen Bradley, specifically designed for SIL3 (Safety Instrumented Level 3) and PLE (Performance Level 4) safety applications. It supports dual or single channel modes and is suitable for signal acquisition of safety devices such as emergency stop buttons and door switches.

 
1734-IB8S core functionality:
1. Input channel: 8 24V DC current input (2 signal consistency can be evaluated in dual channel mode, independent evaluation in single channel mode)
2. Test output: 4 pulse current sources output (for short circuit inspection)
3. Security level: Supports SIL3 and Cat 4 security applications (requires GuardLogix or SmartGuard 600 controller configuration)

1734-IB8S Technical Specifications
1. Power supply: 24V DC (working voltage 19.2-28.8V DC)
2. Power consumption: 3.0W (Ser B)
3. Heat dissipation: 10.25 BTU/hour
4. Size: 77 × 25 × 55mm (without wiring terminals installed)
5. Communication: Supports Ethernet/IP or DeviceNet through adapters such as 1734-AENT and 1734-PDN

1734-IB8S SER-B Type Difference from Ser A
1. Current: Ser B maximum POINT bus current 110mA (Ser A is 175mA)
2. Power consumption: maximum 3.0W for Ser B (3.4W for Ser A)
3. Heat dissipation: Lower for Ser B (10.25 BTU/HR vs. 11.62 BTU/HR for Ser A)

1734-IB8S Application scenarios
1. Security equipment access: such as light curtains, safety doors, emergency stop buttons
2. Industrial Automation: Integrated with CompactLogix and ControlLogix controllers, supporting CIP safety protocol

Condition: Brand new, Original. In stock. With 1 year warranty
