FAQ
FAQ
Q1: What is the Allen-Bradley 1492-TIFM40F-24-2?
A: It is a termination module designed for SIL 2 safety shutdown applications using two ControlLogix 1756-OB16D DC output modules.
Q2: Which PLC modules are compatible with this termination module?
A: It is specifically designed for use with two Allen-Bradley 1756-OB16D DC Diagnostic Output Modules.
Q3: Is the 1492-TIFM40F-24-2 suitable for standard applications?
A: Its primary design is for SIL 2 safety shutdown applications. Use in non-SIL 2 applications is at the user’s discretion.
Q4: What is the maximum current capacity?
A: The maximum current is 1.5 A per circuit and 6 A per module.
Q5: Does this module require a separate power supply?
A: This module and cable combination requires one power source. Separate 24 VDC PLC outputs are required to control the power interruption relays.
Q6: What is the function of the power interruption relays?
A: The two relays allow power to be removed independently from the two connected I/O modules.
Q7: What are the operating temperature and humidity ranges?
A: The operating temperature is 0–60°C, with relative humidity of 5–95%, non-condensing.
Q8: What are the dimensions and shipping weight?
A: The dimensions are approximately 220 × 83 × 70.6 mm, and the manufacturer’s approximate shipping weight is 499 g.
