The use of Weidmüller interfaces in control cabinets enables clear and simple connections between the sensors/actuators of DCS Yokogawa cards. Eliminating the risk of wiring mistakes, saving space in cabinets and reducing the time it takes to build cabinets, are some of the installers' main objectives. The interfaces also offer additional features which provide numerous benefits such as:
Redundancy: the interfaces have 2 40-pole (KS) or 50-pole (AKB) connectors for redundancy purposes.
Many of the interfaces activate a relay to indicate if one of the two possible power sources has dropped below a value of approximately 12 V.
The cards can be mounted via tension clamp or screw connection.
The interfaces can be adequately coated to withstand corrosive environments with a G3 rating (on request)
Multiple functions are integrated: isolators, fuses with status indicator, relay and status LEDs.
This is just a small sample. Other products are also available.
Analogue interfaces are equipped with 40-pole connectors (KS). Versions are available with disconnecting plugs and test points which are extremely useful for voltage and current measurements. There are also versions with useful additional pins for customers who wish to incorporate other elements (resistor ...) for converting voltage/current or monitoring the current loop.
The digital output interfaces via relay are used to isolate the field sensors from the card and/or to adapt the operation of the said elements to the voltage required by the DCS. The interfaces also support additional characteristics that provide many benefits such as:
Redundancy: the interfaces have 2 50-pole (AKB) connectors for redundancy purposes.
Many of the interfaces activate a relay to indicate if one of the two possible power sources has dropped below a value of approximately 12 V
The cards can be mounted via tension clamp or screw connection.
The input sensors can be connected in two ways: supplied with power directly from the card or directly from the field.
