PROCESS DIGITAL INPUT/OUTPUT¶

Introduction¶

The ND 108100 and ND 108110 optically coupled, digital input/output modules are designed for industrial and marine applications for interfacing ND computers to relays, lamps and on/off contacts. Each module occupies one standard I/O slot.

Features¶

12 bits in – 16 bits out
all lines optically coupled
internal programmable Compare Register
contact debounce logic
input signal conditioning

Product description¶

The ND 108100 Input Module contains a programmable 12-bit Compare Register. If the input data pattern and the Compare Register differ, an interrupt is generated.

The ND 108110 Output Module does not generate any interrupts. 16 bits of data are simply loaded into a holding register and immediately become available at the output terminals.

Absolute Maximum Ratings¶

Voltage at terminal DX: relative DX0: -5V, +30V.
Continuous common-mode voltage between computer ground and output terminals DX0 or DX1: ± 30V. Maximum continuous output current: 100 mA. Inductive load should be properly bypassed by a diode.

Switching Characteristics¶

Switching time depends upon load resistance – RE – and pullup voltage Vc. Typical ON and OFF switching times for RE: 1k and Vc: 30V are less than 30 μs.

The following table defines plug connection/Data line definition for both ND 108100 and ND 108110:

Data bit DX1/DX0	Burndy plug pins
D0/D00	A/C
D1/D10	B/D
D2/D20	E/H
D3/D30	F/J
D4/D40	K/M
D5/D50	L/N
D6/D60	P/S
D7/D70	R/T
D8/D80	U/W
D9/D90	V/X
D10/D100	Y/AA
D11/D110	Z/BB
D12/D120	ZZ/EE
D13/D130	DD/FF ND 108110 only
D14/D140	HH/KK
D15/D150	JJ/LL

ND 108100 and ND 108110 modules are referenced in the table for different plug connections.

Process Digital Input/Output¶

Absolute Maximum Ratings¶

Voltage between corresponding input terminals: -15V, +13.5V.

NOTE: DX0, DX1: D – Data - X – Data bit # - Index 0 – -terminal - Index 1 – + terminal

Continuous common-mode voltage between computer ground and input terminals: ±30V.

Switching Characteristics¶

Delay from any change in input to interrupt: 4 ms ±20%. A change in any input line must exceed the 4 ms in order to generate the interrupt. This constitutes the contact debounce logic.

ND 108110 Output Module¶

Number of digital outputs: 16
Operating Temperature: 0 – 55º C
Operating relative humidity: 0 – 90% no condensation

Electrical Characteristics¶

	Min.	Typ.
V_OL - Low level output voltage. @ I_OL = 30mA	0.9V	1V
I_OL - Low level output current	30mA	80mA
I_OH - High level output current @ V_OH = 30V	1µA

Specifications¶

ND 108100 Input Module¶

Number of digital inputs: 12
Operating temperature: 0 – 55º C
Operating relative humidity: 0 – 90% no condensation

Electrical Characteristics¶

	Min.	Typ.	Max.
V_IT - Transition Voltage		5.5V
V_IH - High level input voltage	7.8V
V_IC - Low level input voltage			1.7V
I_IH - High level input current. @ V_I = 12V			9.3mA
I_IL - Low level input current. @ V_I = 15V			0.25mA
