VD SERIES |
Vertex
VD series single digital display controllers are our low cost, yet reliable,
ON/OFF or proportional controllers. This is a very basic controller and not really suited for use with Solid State Relays or Analog output applications.
Ideal for those applications where rough control is OK. Where you need better control use our F Series or VT26 Series. The main feature with this low end
range of controllers is that you can select thermocouple and PT100 inputs
directly from the front panel. You can also select a range closest to your
operating temperature, thereby giving you the most accurate control. They
all come standard with one alarm, and depending on the size can have up to
3 optional alarms.
FEATURES
| Inputs | Inputs are user configurable for all thermocouples and RTD (PT100) from the front panel membrane. Other analog inputs including 4~20 mA are avaliable but must be specified when ordering. |
| Ranges | You can also set any range to suit your application. There are "high" and "low" limits that you can set |
Control Action |
This is a simple controller and so offer as factory default on/off control. You can however also make it a proportional control action controller simply by making "proportional" anything other than 0 |
| Alarms | Each model in the range comes standard with 1 configurable alarm. Up to 3 alarms is avaliable as an optional extra on some sizes |
| Dead Band | There is an adjustable dead band when the controller is used in the on/off mode. This is sometimes reffered to as a "hysterisis" setting. |
| Cycle Time | There is an adjustable "cycle time". This is set primarily to suit the type of control element you are using. For a mechanical contactor it is normally set to 15 seconds, to prevent excessive ware and tear on the contactor. For Solid State Relays it is set to 1 to give a much faster switching time aimed at delivering smaller incriments of energy to the load, thereby making it possible to get tighter control and 0 seconds for analog control |
| Input Filter | There is an adjustabe input filter to smooth the input signal when trying to control those difficult applications |
| Din Sizes | VD2004 ....96w x 96h VD2003....96w x 48h VD2001....72w x 72h VD2000....48w x 48h |
