EP-512: Expansion Module 10 outputs. • You can feed up to 10 outputs 0.3 A each (individual maximum) although the sum of all outputs operating at the same time should never exceed 2 A (total maximum). • The type of output is open collector and connects to negative (NPN transistor), so the other end of the load should be connected to positive. • The maximum operating voltage is 32 V DC. • The presence of food is monitored by a LEO green indicator. • Each output is monitored by a LEO red flag. • It can not work independently and should always be connected to an EP-514 module via EP-513 of a module. • Only used in linear weighers 1 and 2 heads .EN NO CASE MAY BE USED IN Multihead weighers, as it modifies the distribution of the relays and the inputs of the EP-513 and EP-514 modules when connected to them. • Only replace the EP-502 module in linear weighers 1 and 2 heads. Therefore, the module EP-502 is not obsolet. will still be used and will continue to exist parts. • To replace an existing module EP-502 in any of the cases indicated (linear weighers heads 1 and 2) would be necessary to replace the EP-503 for the EP-513 module and EP-514.
