Modicon TM3 counter module. For expanding Modicon M221, M241, M251 and M262 PLC controllers with I/O channels. Compatible with third-party controllers using Modicon TM3 bus couplers. A total of 18 I/Os, including 10 fast inputs up to 200kHz and 32-bit resolution, 8 fast outputs. Inputs can be configured as 10 simple high-speed counters / 2 complex high-speed counters (single phase / dual phase / frequency measurement / period measurement). Configurable reflex function for outputs for minimal response time. The power supply is via 24VDC. The digital outputs are designed as source transistors (0.3A). Project planning and configuration using EcoStruxure Machine Expert software or standalone configurator (download from www.se.com). Connection via removable spring-loaded terminal blocks with a grid spacing of 3.81mm. Ambient temperature during operation -20°C to +60°C. Installation on 35mm DIN rail or directly on control panel with optional bracket. Certifications according to CE, cULus, EAC, RCM.
