Models 8605, 8606, 8607 Analog to Frequency Models 8605, 8606, 8607 analog input modules are designed to interface with the 24 VDC logic inputs for applications requiring additional analog inputs. The 8600 modules output a square wave up to 500Hz allowing the PLC to count the frequency producing about 8 bit resolution, 1 part in 500. power. The output transistor is fully floating allowing either source or sink connection to the PLC. The modules are housed in a plastic case with a built in U-foot for mounting on standard DIN rails. The case dimensions, excluding the U-foot, are 1.65" H x 1.06" W x 3.78" L. Connections are made to screw clamp terminals that accept wire sizes 22 to 16. The 8600 module has an isolated floating optocoupler transistor which provides DC isolation from the input, output and DC Model 8605 Model 8606, 8607 MODEL 8605, 8606, 8607 SINK CONNECTION Model MODEL 8605, 8606, 8607 SOURCE CONNECTION 8605 8606 8607 Input 0 - 20 mA 0-5V 0 - 10 V Output 0 - 500 Hz 0 - 500 Hz 0 - 500 Hz Input Resistance 50 Ohms 100 kohm 200 kohm Resolution 40 µA/Hz 0.01 V/Hz 0.02 V/Hz ±0.015% Typical ±0.01% Typical Linearity ±0.05% of Full Scale Maximum Accuracy (23° ±2°C) ±0.01% Typical ±0.1% of Full Scale Temperature Coefficient (0°C to 55°C) Response Time Over-range Output ±0.003%/°C Typical ±0.015%/°C Maximim Less Than 1 Cycle of Final Frequency 120% 200% 500 Hz Square Wave Floating Optocoupler Transistor 7 mA Minimum current 700 Volts DC 5 pF Power Supply Common Connected to Signal Input Common 12 to 26 VDC 15 - 21 mA Typical Output, Full Scale Isolation Input to Output Transistor Pow er Requirements Voltage Current 120% Environment Operating 0°C to +55°C Storage -40°C to +80°C Siz e 1.65"H x 1.06"W x 3.78"L (42 x 27 x 96 mm) Weight 3 oz.
