HM-104M intelligent multi-channel indicators with high performance HM-104M

Specifications and Product Details:

HM-104M intelligent multi-channel indicators with high performance

Features:

a)Programmable and modular inputs. Multiple input types of thermocouples and RTDs, voltage/current inputs and two-wire transmitters are field- selectable.

b)Every channel can have independent input specification. All channels are equipped with digital adjustment and digital filtering functions and each channel can set different digital adjustment and filtering parameters.

c)High performance hardware design, greatly decreased the temperature drift and the interference between channels, thus multi-channel measurement accuracy is 0.2% full scale, the same as that of single channel.

d)Provide high accuracy compensation function such as ice-point compensation, copper resistance compensation and thermostat compensation to thermocouple inputs.

e)Provide accurate internal calculation functions including addition, extraction, and multiplication.

f)Support up to 2 isolated retransmission output. Any input channel can be retransmitted to OUTP port or all channels are cyclically retransmitted.

g)Provide manual/auto pilot display, with 2 pilot speed selectable.

h)Support up to 7 on-off signal inputs/outputs which can work as alarm output or on-off signal I/O for host computer.

i)Every input channel has independent low/high limit alarm which can be assigned any alarm output.

j)Advanced communication function. Provide high accuracy and stability multi-channel analog data sampling function to host computer. The host computer can also input up to 7 channel on-off signal or execute on-off operation through an indicator.

k)up to 12 field parameters

Ordering Code:

Designed with modular principle, HM-104Mcan be equipped with 6 modules on 6 sockets: M1, M2(MIO), M3(OUTP), ALM, AUX, and COMM. M1, M2 and M3 can be equipped with various input modules, each of which has 1or 2 analog input channels. ALM, AUX and M3 (OUTP) can be equipped with relay output module, each of which has 1 or 2 alarm output channels. When needed, M2 can also be installed with a single relay output module and work as alarm output. COMM can only be equipped with RS485 interface for communication with computer. M2 and M3 can be equipped with either analog input module for measurement or relay output modules for alarm. All inputs and outputs are programmable.

The ordering code of HM-104M is made up of 9 parts, for example:
