Product details

Sourcing Angle

The TM221CE24T: It packs 14 discrete inputs and 10 transistor outputs, plus an Ethernet port and a real-time clock. Fast nickel beats slow dime: if your BOM line needs a compact controller for a machine, this one's a solid plug-in candidate.

Field Service Quick Look

Fast inputs I0, I1, I6, I7 toggle in 5 µs — use them for high-speed counting or pulse capture without an add-on module. Surge withstand at 2 kV common mode on AC power lines keeps this controller alive on dirty mains. Transistor outputs rated for sink or source logic, with overload and short-circuit protection built in at 1 A.

Carries CE marking and complies with UL 508, CAN/CSA C22.2 No. 213, IEC 61131-2, IACS, and ANSI/ISA 12-12-01. Covers most North American and European installs out of the box.

Mounting & Power Backup

Snaps onto TH35-15 or TH35-7.5 DIN rail — no adapter needed. Real-time clock holds for up to one year at 25 °C on a BR2032 or CR2032X lithium battery, so time stamps survive an extended power loss. Memory: 256 kB RAM and flash store up to 10,000 instructions. Data backed up in flash with no battery dependency.

Control & Communication

Supports up to 14 PID loops, PWM, a frequency generator, and high-speed counters (A/B, single-phase, pulse/direction). Ethernet port runs 10BASE-T/100BASE-TX up to 100 m — enough to network with a panel-level HMI or SCADA.
