Digital Input Card.(Part Number VG106DIP16)

One card is essential.
Each card consists of 16 Inputs. Expandable up to 16 cards.
Different type of digital Input cards are available.+24V Input,+12V Input,6 m.a sink or source type.8 switches mini dip type single pole single way is provided on the card .
It is marked with 1 to 8 & it’s ON Position. To select this card as Zero number, marked 1 switch should be in on position & rest switches in off position(Input 0 To 15). Similarly To select this card as One number card, marked 2 switch should be in on position & rest switches in off position(Input 16 To 31). A rack to rack interface card decides it’s upper half position (Input 128 Input To 255).In front 16 green L.E.D's are provided for input status.

Digital Output Card (Part Number VG106DOP16)

One card is essential.
Each card consists of 16 Outputs. Expandable up to 15 cards.
Different type of digital Output cards are available.+24V Output ,50 moa or 1 A sink type.8 switches mini dip type single pole single way is provided on the card .It is marked with 1 to 8 & its ON Position. To select this card as Zero number card, marked 1 switch should be in on position & rest switches in off position (Output 0 To 15). Similarly To select this card as One number card, marked 2 switches should be in on position & rest switches in off position (Output 16 To 31). A rack to rack interface card decides its upper half position (Output 128 Output To 240).In front 16 red L.E.D’s are provided for output status.

Level Translator Card (Part Number VG106LTC16)

This is optional card.
16 Input cards accept 230V A.C Input (8 M.A) & convert to suitable D.C for Digital Input Card. For ease of removing card 230V A.C connections are brought to euro connector. Also a Mothercard and a F.R.C is necessary to connect Level Translator card to Digital Input card. If this F.R.C is to be connected to Digital Input Card 0 then Inputs of Level Controller Card are considered as Inputs from 0 TO 15.If this F.R.C is connected to Digital Input Card 1 then Inputs of Level Controller Card are considered as Inputs from 16 TO 31 & so on.
A 20 V A.C is required as auxiliary power as these inputs are opto coupled.

This is optional card.
16 Output card has relay N.O contact as output. Contacts are rated for 230V A.C 2Amp resistive Load. Relays are driven by Digital Output Card .For ease of removing card 230V A.C connections are brought to euro connector. Also a Mothercard and a F.R.C is necessary to connect Relay card to Output card. If this F.R.C is to be connected to Digital Output Card 0 then Outputs of Relay Card are considered as Output from 0 TO 15.
If this F.R.C is to be connected to Digital Output Card 1 then Outputs of Relay Card are considered as Output from 16 TO 31 & so on. Relay contacts are protected with snubber circuit for inductive loads
