Siemens SM 1231 Series PLC I/O Module for Use with CPU 1211, CPU 1212, CPU 1214, Analogue

To transfer data from your thermocouples to your CPU, choose this PLC I/O Module from Siemens. The 24V DC unit is designed to relay temperature readings via four analogue inputs, with an accuracy of ±0.1 to 0.2%. As it's fitted with alarms and diagnostic messaging, you can monitor the unit's supply voltage to ensure high performance and reliability. Thanks to IP20-rated plastic housing, it's resistant to dust and objects larger than 12mm, so can be used in contaminated conditions.

• -20°C to +60°C operating temperature range for use in demanding environments
• Maximum operating humidity of 95% ensures resistance to non-condensing water vapour
• 180g weight won't add strain to your system

The module has dimensions of 75 (L) x 45 (W) x 100mm (H), so it fits neatly into a busy PLC setup. You can install it vertically or horizontally, according to your needs.

This versatile module is compatible with type J, K, T, E, R, S, N, C and TXK/XK(L) thermocouples.
