The 7214 is a panel-mounted humidity and temperature controller with Honeywell capacitive sensor and four SSR outputs — Heater, Cooler, Humidifier, and De-Humidifier — with proportional PWM for heater and humidifier outputs.
Four SSR outputs: Heater (proportional PWM), Cooler (on/off), Humidifier (proportional PWM), De-Humidifier (on/off). Complete automated environmental control — heating, cooling, humidifying, and dehumidifying — from one instrument.
7214 has four SSR outputs with proportional PWM control (Honeywell sensor). 7217 has two relays with simple on/off control. Choose 7214 for precise four-mode control; 7217 for simpler two-relay applications.
Pharmaceutical stability chambers, cleanrooms, precision incubators, seed germination chambers, museum storage, and electronics manufacturing — anywhere requiring precise four-mode automatic environmental control.
