The DIN-160 Frequency input Modbus modules convert analog input signals to digital data and transmit via RS-485 using the Modbus RTU protocol for communication. The modules perform all signal conditioning, scaling, linearization and conversion to either linearized ASCII data values or Modbus percent of full scale binary values.

	Frequency Input: 1Hz-20Khz.
	Input Impedance: 1M ohms .
	Switching level: selectable 0V, +2.5V.
	Hysteresis: Adjustable 10mV-1.0V.
	Input burnout protection: 250Vac.
	Range: 1Hz to 20KHz.
	Resolution: 0.005% of reading +0.01Hz.
	Accuracy: +/-0.01% of reading +/-0.01Hz.
	Tempco: +/-20ppm/deg C.
