1715-OF8I PLC 8 Point Analog Output Module

Overview

1715-OF8I is the core module of the 1715 series redundant I/O system. It outputs 8 independently isolated 4-20 mA standard current signals. The measurement error is as low as 0.30% + 10μA at room temperature. The accuracy attenuation is controllable after long-term operation in a 40°C environment (error 0.35% + 10μA after 1 year, 0.44% + after 5 years). 10μA), temperature drift is only (0.01% + 0.1μA)/°C; operating voltage 18-32 VDC, backplane current consumption 260 mA (24V DC operating condition), maximum power consumption 3.6 watts, field loop power consumption 0.64 watts; supports 22-16 AWG shielded wire wiring, isolation voltage between I/O ports 50 volts, through 500 Volts AC 60-second insulation test; operating ambient temperature -10°C to 60°C, humidity 5%-95% non-condensing, requires use with 1715-TADOF8, 1715-A310 base module and 1715-TASOF8 termination module.

FAQ:

1.1715-OF8I What are the prerequisites for realizing redundant fault tolerance function? Will the process of switching to the backup module in the event of a primary module failure affect production operations?

1. Hardware configuration: adopt duplex (redundant) working mode, with two 1715-OF8I modules to form a module pair, and equipped with 1715-TADOF8 duplex terminal components and special adapter backplanes (such as 1715-A2A, 1715-A3IO);
2. Network architecture: supports DLR (device layer ring) topology fault-tolerant network, which can be used with 1715-AENTR redundant Ethernet adapter to ensure communication redundancy;
3. System configuration: No additional programming or custom instructions are required. Basic redundancy parameter configuration is completed through Studio 5000 software.

Switching impact: The redundant architecture supports seamless switching, and the terminal components will automatically and smoothly transition the signal to the backup module without manual intervention, ensuring the continuous operation of key processes and minimizing downtime.
