PRODUCT INFORMATION
Product Overview
The Allen-Bradley 1734-VHSC24 is a POINT I/O very high speed counter module for automation control systems. This module processes high-speed counting inputs with a nominal input rating of 24V DC. Input current reaches 6.1 mA at 15V DC and 10.2 mA at 24V DC. The module features one counter channel and four compare windows for precise operational timing.
The field power bus operates nominally at 24V DC with a permissible range from 10 to 28.8V DC. Thermal management yields a maximum power dissipation of 1.9 watts at rated load. This power dissipation equals a thermal dissipation rate of 6.5 BTU per hour. The physical module utilizes an open-style enclosure and requires keyswitch position 2 for base mounting.
