Remote Terminal Unit 32 contact inputs RS485 (Modbus-RTU) IEC61000
1. General
PZ-K32 can accepts 32 actives or passive contact signals. It is connected to master device or computer with an RS485 interface and reply the data of contact state on a real-time. At the same time it can store 1600 events (SOE) to accurately indicate the time of the change of contact state.
2. Technical feature
- Input 32 Passive Dry Contacts or 32 Active Wet Contacts Response time < 2ms Scanning time 1ms- Power Supply Voltage range 24 VDC(18-36VDC) or AC/DC 80-270 Consumption ≤ 5W- Communication Bus Mode 2-wires half-duplex RS485/Modbus protocol Bus Capacity ≤ 32 Response Time 20ms Baud rate 9600 / 4800 / 2400 / 1200 bps - Capacity of Sequence of Events (SOE) ≤1600
There are 1600 SOE. Each SOE has 8 registers and 16 bytes. The first register is from register25.- Degree of Protection IP40, Terminal IP20- Isolation 2Kv/1min,50Hz ( inputs, output and supplier)- Work Temperature -5C - 55C - Storage Temperature -25C - 85C- Mounting TS35 Standard DIN rail - Dimention 160 × 50 ×110mm- StandardsIEC61000-4-2: 1995 Electrostatic discharge immunity test Level 3IEC61000-4-3: 1995 Radiated, radio-frequency, Level 3 electromagnetic field immunityIEC61000-4-4: 1995 Electrical fast transient pulse immunity test Level 3IEC61000-4-5: 1995 Surge immunity test Level 3EN55022: 1998 Information technology equipment(ITE) Level B
