Usage Introduction: The most widely used SSR signal processing controller in industrial electric heating systems, which can accept PWM or 4-20mA input, generate two types of outputs: cycle zero crossing (PWM duty cycle control) and cycle zero crossing (CYC variable period), and directly drive SSR or Xi SW03A or TC32A thyristor power expanders. Due to the uniform distribution of the load current according to the sine wave, and the randomness and superposition of multiple equipment operation, the total power load current is relatively balanced, which improves the adjustment accuracy and power utilization efficiency, as well as avoids meter tapping and power equipment capacity increase
I Main technical indicators:
Optical isolation input P-type: pulse width modulation (duty cycle) pulse, cycle: 2 seconds; High level: 4-15V; Low level: 1.5V; Maximum input current:<20mA optical isolation
Voltage>2KV DC (one second test)
4-20mA input type I: acceptance impedance<250 ohms
Adapted interface: Shimada P or I type PID regulator or DCS output interface.
Output: 0-12V pulse, maximum driving current: 60mA
Automatic/manual selection: selection of external voltage free contact switches
Internal MS output mode: selected by the jumper insertion terminal 1) PWM duty cycle output 2) Cycle wave CYC output
Internal power limit: Internal potentiometer P1 adjustment (factory not limited) Limit range: 0-100%. Note: It fails in manual or PL mode.
60 second power on slow start: starts when powered on for the first time or manually switched to automatic mode, used to reduce the average power of cold start.
Indicator light: PWM signal or 4-20mA input green LED; Red LED output indication.
Load connection method: 50Hz single-phase or three-phase delta or star center ungrounded/grounded, two control three-phase pure resistance load, no phase sequence.
