CLT3-4BT6-TR

The CLT3 - 4 is a quadruple input digital termination device designed for 24 V dc automation applications. It provides the front - end circuitry of a digital input module (I/O) in industrial automation, and drives an isolating opto - coupler.

Applications

• Industrial automation
• Programmable logic controller
• Communication field bus nodes
• Peripheral input / output modules
• Machine tool interface

Key features

• 4 channel topology
• Wide range input dc Voltage:
• -Vi = -0.3 to 30 V with Ri = 0
• -Vi = -30 to 30 V with Ri = 1.8 kΩ
• Low side configuration with common ground
• Current limiter:
• -IGEN = 3 mA
• -Input current limit activation voltage < 5 V
• Temperature compensated operation
• Opto - coupler drive: No coupler activation below 1.5 mA input current
