Single-channel resistance-temperature input board for compatible SIMATIC S7-1200 CPUs
Siemens 6ES7231-5PA30-0XB0 is a SIMATIC S7-1200 SB 1231 RTD signal board for one resistance-temperature input. It plugs directly into a compatible S7-1200 CPU and supports platinum RTD and resistance measurement for compact temperature-monitoring applications. Siemens specifies a 24 V DC rated supply, 15-bit resolution plus sign, diagnostic alarm and wire-break diagnostics. Supported platinum sensors include Pt100, Pt200, Pt500 and Pt1000. The official lifecycle wording is Phase Out Announce. Confirm the complete order number, target CPU, hardware catalog support, sensor type, wiring, shielding and project configuration before ordering or replacing an installed board.
