It provides continuous, easy-to-read documentation on a large 12-inch circular chart and features simple keypad programming for quick setup right on the floor. Dual pens (red/green) record two independent channels (e.g., product & CIP) on the same 12" chart. Universal inputs : 100 O RTD, 4–20 mA, 0–5/1–5 V, and J/K/E/T/R/S/B/N thermocouples. NEMA 4X enclosure withstands wash-downs and high humidity; panel or surface mount. Modular outputs : up to four relays and up to two isolated 4–20 mA re-transmits. Optional PID control on one or both pens (auto/manual, remote setpoint). Bright LED displays —one per pen—for quick, at-a-glance readings. 3-year manufacturer warranty from Anderson-Negele.
