Basic performance of WPL temperature inspection instrument
■ 8 ~ 80 input channels, aluminum alloy shell, plug-in terminal blocks.
■ 0.2-level accuracy, measurement and control speed of 0.1 seconds or 0.2 seconds per channel (thermocouple channel).
■ Can input thermal resistance, thermocouple, DC current, voltage signal.
■ 2-digit channel number display, 4-digit measurement value display, display range -1999 ~ 9999.
■ The thermal resistance display resolution is 0.1 ℃, and the thermocouple display resolution can be set by parameter 1 ℃ or 0.1 ℃. (Each channel is set independently)
■ Can set the total number of channels used. You can also arbitrarily close the channels that you don't care about temporarily so that they do not participate in the tour display and alarm comparison.
■ Each channel independently sets the signal type and range.
■ Each channel independently sets the digital filter time constant to improve the display stability.
■ Zero and full-scale correction are set independently for each channel to improve system measurement accuracy.
■ With fixed-point display function, easy to adjust.
■ With parameter copy function, parameter setting can be performed quickly, greatly reducing the workload of parameter setting.
■ Standard communication interface, optional RS232 and RS485, ASCII protocol or MODBUS-RTU protocol
■ Optional printing function, can realize manual, timing, alarm printing.
■ Alarm function
① Each channel has 4 independent alarm settings and independent upper or lower alarm modes.
② Independent alarm indicator for each channel.
③ 4-point alarm output, 2 configurable alarm output modes
Method a: Working mode of flash alarm
The first alarm output: Any channel is closed when it enters the alarm state from a non-alarm state; automatic delay recovery (confirmation) or panel key recovery (confirmation).
2nd point alarm output: As long as 1 channel is in alarm state, it will be closed.
The alarm indicator of each channel has 3 states
① Not lit: The channel is in a non-alarm state
② Blinking: It indicates that the channel enters the alarm state from the non-alarm state, and there is no automatic delay confirmation or panel key confirmation.
③ On: The channel is in alarm state and has been confirmed.
Method b: Two alarm setpoint sharing methods for each channel.
1st point alarm output: The 1st alarm setpoint of any 1 channel is closed in the alarm state.
2nd point alarm output: The 2nd alarm set point of any 2 channels is closed when it is in the alarm state.
3rd point alarm output: The 3rd alarm set point of any 3 channels is closed in the alarm state.
4th point alarm output: The 4th alarm set point of any 4 channels is closed in the alarm state.
