J1, AC Line Input 
  This is 115 VAC line power and ground connection to the unit. Note, depending upon local 
codes grounding may also need to be provided from the steel plate which supports the main board. 
 
 
 
 
 
The non-metallic enclosure does not provide grounding 
from any conduit connections. Always use a ground wire   
from the external power...

When configured for 4-20 mA each of the inputs presents a load of 250 Ohms to ground for 
the external circuit, so each input may also be used for a 0 to 5 Volt DC input providing the external 
circuit is capable of driving the load. On the 8ADI-9DO each analog input is protected against external 
overloads to approximately 40mA, or 10 Volts DC, and on...

  If possible each input should have its own current return (the odd numbered pins on these 
connectors) to maintain highest accuracy, however they may share ground connections in some 
cases to save wiring. Do not use the system ground as a return for the current loops when using an 
external...

J12, J3 Local Contact Inputs 
  These are transient protected, dry-contact switch or logic level inputs to the RFScada device. 
Each of the inputs is pulled up to 5 Volts DC via a 1K Ohm resistor, so the inputs may be activated 
either by a shorting switch contact to ground or they may be directly driven from an ‘open collector’ 
logic level. 
 
 
  Each...

be disabled by moving a jumper on the board. All the software settings are unaffected by this jumper; 
it merely physically disables power to the relay. Once the system has been verified fully operational 
the jumper may be placed in the power save position; of course it may be placed back in the normal 
position to verify correct operation at any time....

electronic fuse tripping. If this occurs remove DC power, wait a few seconds then restore DC power; 
normal operation should resume.  
The 4ADI-5DO unit is diode protected from reverse polarity, has an electronic fuse protecting 
the on board components, a mechanical (2A 250VDC) fuse protecting the ‘pass thru’ external radio 
connection (J17) and is also...

The fuse will blow if there is a malfunction in the circuit, or a voltage greater than the board rating is 
applied to the AC line input. The fuse is located underneath a safety cover. To test and replace the 
fuse proceed as follows: 
First remove the AC and DC (if used) power to the unit. Then open the unit and unplug the AC power 
connector J1 to allow...
