SQC2200U

The Danaher SQC2200U is a high-performance counter module from the Timers and Controllers series, designed for robust industrial automation tasks. Manufactured by Danaher, this compact unit delivers a maximum count up to 99,999 at speeds reaching 5,000 counts per minute while maintaining manual reset capability and retaining its preset after any reset. Featuring a two-line LCD display with LED backlight housed in a 1/16 DIN panel footprint, the SQC2200U combines intuitive operator feedback with streamlined panel integration. The counter’s weight of 2 lb 9 oz and its depth of 143 mm ensure a low-profile installation without sacrificing durability or functionality.

The SQC2200U’s technical capabilities center around its versatile input and counting modes. It accepts both AC Input (85 to 260 VAC) and DC Input (10 to 26 VDC), drawing up to 6 VA on AC and 0.4 A on DC, while delivering a Count Rate of 2.4 kHz. Count input modes include switch input and contact closure, supporting a maximum input frequency of 20 Hz with a minimum pulse width of 20 ms. This module offers quad and add/subtract counting, as well as dual preset registers (Preset 1 and Preset 2) with six-digit length, plus calibrator and decrement reset modes. Outputs are provided via a relay rated for 5 A resistive at 120 VAC or 24 VDC, and 3 A resistive at 240 VAC, with an adjustable output time range from 0.01 to 99.00 seconds.

Operational features of the SQC2200U emphasize reliability and ease of use. The front panel carries a Protection Class rating of IP65, safeguarding the display and controls against dust and water ingress. A front-mounted push button allows for both automatic and remote reset operations, while pluggable screw terminals simplify field wiring. Accessory power is regulated at ±12 VDC with 25% tolerance, ensuring stable operation of external sensors or indicators. Operating temperatures from 0 to 50 °C and the geared 1:1 drive shaft (1/4-inch) support demanding process environments and precise mechanical interfacing.

Integration with existing control systems is straightforward: the SQC2200U fits standard 45 × 45 mm panel cutouts and communicates via conventional relay contacts and TTL-compatible inputs. Its compact dimensions (48 × 48 mm front panel) and industry-standard mounting pattern allow seamless replacement or upgrade of legacy counters. Applications span batch control, item counting, production monitoring, and automated quality checks across packaging, material handling, and manufacturing lines. With its combination of flexible voltage inputs, multiple count modes, and robust construction, the SQC2200U offers a reliable solution for diverse industrial automation challenges.
