Product details

The TM221C16R is a compact Modicon M221 logic controller from Schneider Electric — 16 discrete I/O, 10 transistor inputs (sink/source) and 6 relay outputs rated for 2 A per point. The controller supports up to 14 PID loops, a real-time clock with battery backup (BR2032), and 256 kB RAM for application and data. Communication is handled through a serial link (RS232/RS485) at up to 115.2 kbit/s, a USB port at 480 Mbit/s, and a CANopen master interface. The on-board Ethernet port (not present on this variant? — check: not in evidence, so omit) is not listed; connectivity is via the serial and USB channels.

Snaps onto a standard TH35-7.5 or TH35-15 DIN rail per IEC 60715, or can be panel-mounted using a fixing kit. Operating altitude 0–2000 m, storage altitude 0–3000 m. Pollution degree ≤2.

I/O and performance details

Fast inputs (I0, I1, I6, I7) respond in 5 µs on turn-on and turn-off, suitable for single-phase, dual-phase quadrature, and pulse/direction counters. Other inputs slower at 35 µs turn-on / 100 µs turn-off. Discrete inputs have 3.4 kΩ impedance; analog input channel has 100 kΩ. Relay outputs switch up to 20 operations per minute at maximum load. Minimum switching load is 1 mA at 5 V DC — be aware of this if driving very light loads. Outputs are isolated from the logic at 1500 V AC, with common-mode surge withstand of 2 kV.

Carries CE marking and complies with IEC 61131-2, UL 508, CAN/CSA C22.2 No. 213, IACS, and ANSI/ISA 12-12-01. This covers industrial control equipment and hazardous location approvals (Class I, Division 2). Insulation coordination is specified with clear voltage levels between inputs, outputs, supply, and ground.
