Excellent PLC
Product Introduction
The Allen-Bradley 1771-OFE1 Analog Voltage Output Module is a high-precision analog voltage output module designed for the PLC-5 1771 I/O system by Allen-Bradley. It provides accurate analog voltage outputs for controlling industrial field devices, actuators, and instrumentation in automation systems. The module translates digital PLC signals into reliable 12-bit voltage outputs, making it ideal for process control applications requiring fine resolution and quick response.
The 1771-OFE1 supports four output channels and offers selectable data formats in either BCD or natural binary. With a converter setting time of 0.8 ms and an internal scan rate of 8 ms, it ensures timely and precise analog signal delivery. Drawing 1.5 A from the backplane and dissipating a maximum of 7.9 W, the module is optimized for stable operation in PLC-5 systems and industrial environments.
