Allen Bradley 1756-IV16

The Allen-Bradley 1756-IV16 is a digital sourcing I/O module. This input module has 16 inputs available, with 8 points in a group. Compatible with the ControlLogix 1756 chassis, it requires a removable terminal block housing, or RTB, which can either be the 1756-TBNH or 1756-TBSH before it can be attached to the chassis. Only an input data format is used by this module. The operating voltage range of the 1756-IV16 module is from 10 to 30 Volts DC and it has a 12/24 Volt DC source voltage category. It also has a nominal input voltage of 24 Volts DC. Its total backplane power is 0.61 Watts and maximum inrush current is 250 milliamps. The 1756-IV16 has a maximum input impedance of 3.2 kΩ at 30 Volts DC, a maximum power dissipation of 5.1 Watts at 60 Degrees Celsius, and a thermal dissipation of 18.47 BTU/hour. It also has a continuous isolation voltage of 250 Volts. During an off-state, this module has a maximum voltage of 5 Volts DC and a maximum current of 1.5 milliamps. When it is in an on-state, the 1756-IV16 has a current range of a minimum of 2 milliamps at 10 Volts DC and a maximum of 10 milliamps at 30 Volts DC. The 1756-IV16 module has a screw to backplane input delay time. This varies depending on if it going from an 'off' to 'on' state or vice versa. The input delay time when going from 'off' to 'on' is the hardware delay (with a nominal of 280 microseconds and a maximum of 1 milliseconds) plus the user-selectable filter time (either 0 milliseconds, 1 milliseconds, or 2 milliseconds). If going from 'on' to 'off, the input delay time is the hardware delay time (with a nominal of 540 microseconds and a maximum of 2 milliseconds) plus the user selectable filter time (either 1 milliseconds, 2 milliseconds, 9 milliseconds, or 18 milliseconds).

FAQ

1.Q:Other suppliers have a better price than yours?

A: ''To create the greatest benefit for clients'' is our belief, if you have a better price, please let Wusu know. We will try the best to meet your target price and support you.

2.Q:What's the delivery time ?

A: Normally we have enough stock for regular models(such as PLC FX3U-64MR/ES-A ) and we can deliver immediately at the same day after payment received. For some products that is not in stock, we normally deliver within one week.

3.Q:What is the standard of package?

A: Export standard package or special package according to customer requirement.

4.Q: Could Wusu provide technology support?

A: We're in this field for more than 15 years and we have our own technical team. Our engineer could give suggestion and help to solve the problem if there's any problem.

5.Q:Does Wusu keeps goods in stock or only trading?

A: We have warehouses in Guangzhou and HongKong and keep large stock of goods in it, that's how we promise fast delivery.
