| Input Specifications |
| Input signal: universal signal input for all channels with signal type configured by parameters. |
| SeeInput Signals for details. |
| Channels: 6 channels; enabled by the parameter settings. |
| Isolations: No isolations between channels |
| (Not applicable for applications with common-mode voltage between channels) |
| For voltage input channel, if the input voltage is larger than about 5.5V, the channel will enter the protection mode and the operations of other input channels will also be affected. However, this will not damage the input module. Once the input signal returns to the normal operating range, the module will return to normal measuring state as well. |
| Input channels are isolated from communication and external power supply. |
| Measuring 1 second (6 channels are enabled) |
| cycle: Measuring rate is also influenced by input signal configuration parameters and time constant of digital filtering. |
| Basic error: ±0.2 %F•S |
| For type B thermocouple input, the accuracy cannot be guaranteed when the temperature is below 400ºC. |
| Accuracy of cold junction compensation: dependent on cold junction compensation approach, thermal equilibrium conditions of the terminal, and cold junction compensation coefficient. |
| Communication Specifications |
| Interface: RS485 |
| Isolation: isolated from signal input channels and external power supply |
| Protocol: Modbus-RTU (slave mode) |
