Remote terminal controler/RTU PZ-M32

Remote Terminal Unit 32 0/4-20mA / 0-5V analog inputs RS485 (Modbus-RTU) IEC61000

1. General

          PZ-M32 is applicable in intelligent systems remotely measuring analog signals, like current, voltage, power, temperature, pressure and humidity etc... PZ-M32 can accept 32 ways AC/DC 4-20mA / 0-20mA or AC/DC 0-5V analog signals. It is connected to master device or the computer by RS485 communication to transfer the data on a real-time.

          It has 32 alarms LED with 3 colors to indicate the state of 32 analog inputs. We can set 2 points alarms (maximal and minimal value) as well as the delay of the alarm.

3. The description of LED for analog input alarm

PZ-M32 can indicate the states of all the analog inputs. By 2 Rs485 communications, we can set maximal and minimal values alarms as well as the delay of alarms. It has 32 LED with 3 colors to match each analog input.

Description LED:

OFF: no input

Green: work well, the analog input value is between maximal and minimal alarms.

Red: on the state of maximal value.

Orange: on the state of minimal value.

4. Examples

Examples1

Read 1st channel analog value on device02 (by order 03H)

Request: 0x02,0x03,0x00,0x0D,0x00,0x01,0x15,0Xc9

Reply:   0x02,0x03,0x02,0x13,0x00,0Xb5,0x74

Explanation: On device02, its 1st analog input value is 4.864.

Examples2

Set the maximal value of 1st alarm on device01 (by order 06H)

Request: 0x01,0x06,0x00,0x2D,0x3E,0x80,0x09,0xC9

Reply:   0x01,0x06,0x00,0x2D,0x3E,0x80,0x09,0xC9

Explanation: set the maximal value of 1st alarm as 16.000

Examples3

Read the states from 1st channel to 5th channel on device01 (by order 02H)

Request: 0x01,0x02,0x00,0x00,0x00,0x05,0xFC,0x09

Reply:   0x01,0x02,0x01,0x0C,0x51,0x8D

Explanation: 0C to binary is 01100. That’s to say that there are 2 alarms, channel 3rd, 4th. Others work normally.
