VOSER – XV. Adjustable voltage/current sensitive relay control Board with delay.

The VOSER-XV board is designed to perform relay Lead/Lag control "window" switching function based on three set points. 

1. "On" voltage/current set point ("CUT-IN", Relay Engage).

2. "Off" voltage/current set point  ("CUT-OUT", Relay Dis-engage, Relay Un-engage).

3. "On time Delay" set point  ("CUT-IN-DELAY").

Shown above configured for voltage Input 0-30V DC.

The board can accommodate many industrial standards inputs both, voltages and currents configurations:

1. Input current: 4-20mA (or 0-20mA), 0-100mA

2. Input voltage: DC 0-5/10/15/20/30/40/60/150/300V

If used properly, it will eliminate the need for expensive boards, which would otherwise be needed to carry out the same tasks, or pricey PLC.

The VOSER-XV is easy to install, setup and operate. If you want to do professional relay window switching via setting of voltage or current with On-delay, The VOSER-XV offers the features you need.

As mentioned above, the board can be configured to accept many input signals low voltage and current, as well as High Voltage Signals (HVS).

Mounted easily via two 0.125" mounting holes using 4-40 screws (optional) and wire via convenient conventional industrial standards cage up terminal blocks (TB).

Setting the board is simple Just follow these easy steps

1. Power the module Connect the board to 10 to 24V AC or DC. Preferred stable 24V DC (industrial standard).

2. Connect Digital Volt Meter DVM between Test point common ground (TPG, COM) and three test point.

Set three set points on by on as desired. Test (T) point T-On (TP1, "cut-in"), T-Off (TP2, "cut-out") and Delay (TP3, Delay). (or we will pre-set it for you).

3. Connect the signal.

The board remembers the setting points and the relay will turn on (engage) after time delay, and off (dis-engage).

The board is ideal when an analog signal is required to switch two position (thresholds window) loads i.e. Flow alarm, circulating pumps, high and low fan speeds, humidifiers, pool chlorine feeding pumps, sensor level switching functions, differential switching controls, analog signal to relay on/off (cut-in/cut-out) threshold window, analog signal voltage, or current alarms and more.

Sample configurations

Sample 1.0

Shown above when configured for current signals input, where relay threshold window:

 On (cut-in) set @ 24mA and  off (cut-out) @ 12mA.

Normal operation where I_On > I_Off settings.

Sample 2.0

Shown above when configured for voltage (0-30) signal input, where relay threshold window:

On (cut-in) set @ 10VDC and  off (cut-out) @ 5VDC

Normal operation where V_On > V_Off settings

Sample 3.0

Shown above when configured for voltage (0-30) signal input, where relay threshold window:

On (cut-in) set @ 5VDC and  off (cut-out) @ 10VDC

Auto-Reverse operation where V_off > V_On settings

Note: In all above sample configurations the delay automatically set to 1 second (without delay option) or with delay option of 1-255 second (up to 4 minutes and 15 seconds). If required we can pre-set or change the delay timer as requested.
