Does the Honeywell PKS have a special card that is used to sense temperature? What is its name?

There are specialized cards that accept thermistor signals, in a three-wire system. There are also cards designed to receive thermocouple millivolt signals. It’s relatively expensive.

So what names? For example, AI, AO, DI, DO

Multi-channel low-level analog input card

Typical remote temperature transmitters convert resistance or mV voltage signals into 4-20mA current signals, which are then sent to ordinary analog input cards. If you want to send the resistance signal directly to the control system, you need to use a three-wire or four-wire configuration along with a dedicated temperature input card; however, the downside is that this approach is not cost-effective and results in lower measurement accuracy. If you want to send the mV signal directly to the DCS, the same problem arises: you need to use compensation wires for compensation (which are quite expensive), as well as a dedicated mV card. The disadvantages are the same. Therefore, these two types are no longer widely used and have gradually been phased out by the market. The multi-channel low-level analog input card mentioned on page 4 is a term used in Siemens PLC systems; if you want to inquire about such cards, it’s best to contact the manufacturer from HN

The HN pks system has a card of this type: the LLMUK multi-circuit low-level analog input card with an FTA wiring panel, which can be connected directly to thermocouples or thermal resistors; the wiring methods differ. You on the 5th floor, take a good look at what they’re asking

The temperature card for HW isn’t actually expensive; it’s quite cheap! Is there a misunderstanding? The classic HW temperature card has 64 channels per card. Then divide into 4 groups. 16 points per group. Each group can be individually set to PT100, K-type TC, B-type TC, etc. In this way, one card is connected to 4 temperature-specific FTA units, with each FTA having 16 channels. Calculated this way, the cost per unit is actually quite low. But objectively speaking, is this the way to play? The card holder isn’t very reliable. . . PlantCruise first developed a temperature-specific card with 16 channels per card. Each channel can be individually configured as RTD or TC. It is no longer 64 channels per card. The latest version of the PKS C series will also introduce a temperature-specific card with 16 channels per card.

Yes, the model is LLMAX
